71-year-old Jerrold Chaleff had been walking in a parking lot inside a shopping center on Bartow Avenue near Co-Op City Boulevard about 9 a.m. when he was struck by a Ford Focus driven by Ruben Delgado, 79, sources said.

The victim was taken to Jacobi Hospital, where he died a short time later.

Delgado was questioned at the scene but was not charged with a crime, and no summonses were issued, police said.
